Water flowing through a pipe of area of cross-section \(2 \times 10^{-3} \mathrm{~m}^2\) hits a vertical wall horizontally with a velocity of \(12 \mathrm{~m} \mathrm{~s}^{-1}\). If the water does not rebound after hitting the wall, then the force acting on the wall due to water is
- A 24N
- B 144N
- C 288N
- D 72N
Answer & Solution
Correct Answer
(C) 288N
Step-by-step Solution
Detailed explanation
\( F = \rho A v^2 \) \( F = 1000 \times (2 \times 10^{-3}) \times (12)^2 \) \( F = 288 \mathrm{~N} \)
